Galatasaray Üniversitesi Matematik Bölümü SeminerleriReal 3-manifolds can be obtained from real 3-sphere via surgery Ferit Öztürk
A real 3-manifold is a 3-manifold with an orientation preserving involution. 3-sphere has a unique real structure with nonempty fixed point set up to equivariant isotopy.
It is well-known that every 3-manifold can be obtained from the 3-sphere via +1 and -1 surgeries along a finite collection of knots. In this talk we will prove that any real 3-manifold can be obtained from the real 3-sphere via surgery along a finite "recursively invariant" collection of knots.
